Title: Manufacture of semiconductor device
Inventor: KUNIKIYO TATSUYA
IPC: H01L21/336
Filed: 1990-09-06
Abstract: PURPOSE:To suppress the deterioration of a gate oxide film by a method wherein a gate is formed on a substrate and thereafter, silicon is implanted in drain regions for N<-> layer formation and a polysilicon region and after this, an impurity for drain formation is implanted and the impurities are electrically activated in such a way as to perform a heat treatment. CONSTITUTION:Boron is channel-doped to a silicon substrate 1 and thereafter, a gate oxide film 2 is formed. Then, a polysilicon film 3 is deposited and the films 2 and 3 located at regions other than a gate are removed by etching. After this, a resist 5 is deposited on regions other than regions, where are used as drain regions 6 for N<-> layer formation, and the gate region and silicon is implanted in the regions 6 for N<-> layer formation and the polysilicon region using this resist 5 as a mask. Then, the resist 5 is removed, an oxide film 4 is formed on the gate and arsenic is ion- implanted using this film 4 as a mask to form N<-> layer. After this, after an oxide film is deposited, sidewalls 9 are formed by anisotropic etching and arsenic is implanted to form N<+> layers 8. After this, each impurity enters the position of the lattice of a silicon crystal by a heat treatment and is electrically activated. Thereby, gentle concentration distributions can be respectively obtained from a channel region toward the drain layers.

Title: Eccentric vacuum pump
Inventor: KONDO KOJI
IPC: F04C25/02
Filed: 1990-09-07
Abstract: PURPOSE:To reduce noises and largely extend the life of a pump by forming relief grooves relieving part of the air surrounded by adjacent blades and the inner periphery wall of a cylinder at the time of discharge in the compression stroke on a blade. CONSTITUTION:The air sucked into a pump chamber is extruded by a blade 16 and compressed in the pump chamber as a rotor 2 is rotated. When a blade 17 reaches the position sliding on a leak groove 8 (discharge start position), the compressed air in the pump chamber starts to be discharged from the leak groove 8 via a discharge port 21. After the blade 16 passes the discharge start position, the pump chamber and a rotor space section 2a are communicated. Part of the air in the pump chamber surrounded by the blades 16, 17 passes the relief grooves 24, 25 of the blade 17 and is relieved to the rotor space section 2a. The over-compression of air in the pump chamber between the blades 17, 16 is prevented, and this over-compression preventing effect is effective at the time of high-speed rotation in particular.

Title: Heat treatment device
Inventor: MIYAZAKI SOICHIRO
IPC: B23K1/19
Filed: 1990-09-07
Abstract: PURPOSE:To shorten a tact time by a method wherein as it approaches from near an inlet door to an outlet door, an in-furnace set temperature caused by a heater is gradually increased and at the same time a set temperature near the outlet door is set to be lower than a set temperature in the heating zone just before it. CONSTITUTION:An inner wall of a heating chamber 15 is provided with a reflection plate 13 and a heater 12 over a substantial entire length within the heating chamber 15. A set temperature of the heater 12 is set as a set temperatures T1 to T5 in which the heating chamber 15 increases in an upward stepwise manner from the first heating zone 1st to the fifth heating zone 5th and at the same time the sixth heating zone 6th and the seventh heating zone 7th are lower in a downward stepwise manner lower than the fifth zone 5th. For example, if a final reaching temperature of an aluminum heat exchanger core is 600 deg.C, T5 is 610 deg.C, T7 is 600 deg.C. In this way, a reason why the set temperature T within the furnace is slightly higher than a final reaching temperature of the core consists in the fact that as long as the heater is heated within a limited time, a temperature of the core is always higher than the set temperature of the heater.
